Description
The present invention relates to a kind of synthetic resin hook that in analogs such as various bags, knapsack, uses.
In recent years, people more and more use synthetic resin hook to come the alternative metals swivel hook, and this is that its required amount of parts is less because synthetic resin hook is compared with the metal swivel hook, and synthetic resin hook can guarantee preferable productivity ratio, and weight is light and low price.On the contrary, the metal swivel hook then needs a large amount of parts, and therefore, its assembling work just needs more step, thereby causes its price higher.In addition, because the metal swivel hook is difficult to paint durable color, therefore, it lacks fashionable outward appearance, so be not suitable for traveling bag, shoulder bag or other analog.Therefore, the use of metal swivel hook only limits to some specific regions, for example expensive commodity.
In disclosed Japan Patent publication No.9-32839 for example, disclosed an example of synthetic resin hook.This synthetic resin hook comprises: a coupler body that comes out from the base portion projection; And one from this base portion, come out and can be around the retainer of its bottom strain towards the projection of coupler body top.Described coupler body or retainer have one from its inner surface, towards retainer or be arranged on the projection that the coupler body projection of bottom end vicinity is come out, and this projected front ends height is to set like this, promptly, when retainer is out of shape, in the elastic limit of described bottom, described projection can contact with retainer inner surface or coupler body inner surface.
In the swivel hook that this publication disclosed, because coupler body and/or retainer have projection, described projection has the ideal height that is positioned at the counter pair on its bottom inner surface towards, even a very big external force is acted on the bottom of retainer, with aforementioned projection, can prevent that retainer from the distortion of elastic limit taking place to surpass, like this, just can prevent the bottom fracture of retainer reliably, and described bottom is the part of the easiest fracture.In addition, since be provided with this projection can prevent one link to each other with belt ends and and the ring that meshes of coupler body move between coupler body bottom and the retainer, even one external force is acted on the outside of coupler body with described ring, described ring also can be with projection and is moved to its front end from the bottom of retainer, thereby the bottom that can prevent retainer is impaired.
But, in the swivel hook that above-mentioned publication disclosed, owing to be provided with the projection of coming out from the inner surface projection of coupler body or retainer, therefore, in this projection with after the opposed inner surface of retainer or coupler body contacts, when retainer during towards coupler body inner surface direction strain, a rotation bottom will move to an edge of the projection on the side from the projecting end on the described base portion towards coupler body one front end, and rotation amount is greatly diminished.Therefore, form an open space that is enough to make the ring that links to each other with belt to be meshed if desired with coupler body, so, the degree of depth of described coupler body and highly must be greater than traditional coupler body.As a result, will produce an adverse consequences, that is, swivel hook itself will be exaggerated.If an external force that surpasses above-mentioned elastic limit is put on the described retainer in the place of relative projection near the coupler body front end, then described retainer may rupture at the raised edges place on the coupler body front end side.
As for example U.S. Patent No. 5, that is disclosed in 146,657 is such, and traditional synthetic resin hook is formed the front end outer surface that retainer departs from coupler body slightly, and after being shaped, retainer generation strain and be engaged in and be positioned on the mating surface of coupler body front end.Therefore, for this reason and the workload of carrying out is can not be unheeded, so just production cost just there is to a certain degree influence.
Therefore, the present invention is intended to address the above problem, its purpose is to provide a kind of like this synthetic resin hook, and wherein, the length of a coupler body and the degree of depth can be configured to as traditional swivel hook, one retainer is than the easier strain of traditional swivel hook, like this, if a very big external force is put on the above retainer of retainer may rupture, and retainer can be made into like this with regard to not worrying, that is, need not special operation just can make it contact with the inner surface of coupler body.
Above-mentioned purpose can be realized effectively by the present invention.
According to the present invention, a kind of synthetic resin hook is provided, it has: a coupler body from the base portion extension; And a retainer, it extends upwardly to a curved end of described coupler body, and can center on its bottom strain, is characterized in that described retainer comprises: one from bottom that described base portion projection is come out; One curved portions, it and described bottom form one, and towards the c-shaped substantially or U-shaped of an inner surface projection of described coupler body, and between described bottom and described coupler body outside opening; And a tongue spare portion, it from described curved portions extend upwardly to described coupler body curved end one in mating surface.
The described bottom of described retainer is not directly related with strain, and makes: even a very big external force is applied thereto, can not rupture in its bottom yet.On the other hand, although described coupler body and band connecting ring on design, structure and working effect with traditional different, described coupler body and band connecting ring are with traditional that what does not have is different.
If the external force of a common size is put on the tongue spare portion of described retainer, the major part of this external force will be used for the strain of curved portions, and like this, the front end of tongue spare portion just can contact with an inner surface of coupler body swimmingly.If remove aforementioned external force, described curved portions will be returned to its original-shape.By described restitution, its home position will be got back to by tongue spare portion, thereby its arc tips place at coupler body is contacted with interior mating surface.If a very big external force is acted on the bottom of described retainer,,, and can and then not rupture so described bottom strain can not take place yet because its hardness and intensity will be higher than other parts.In addition, described retainer has a barrier effect for described curved portions, can prevent that thus curved portions and tongue spare portion from rupturing.
The aforementioned structure of retainer of the present invention is effective for making swivel hook expeditiously.Usually, when molded, when a molded products is taken out from the injection moulding die cavity, described molded products will shrink.Especially when molded products during c-shaped or U-shaped because the Temperature Distribution difference of molded products when molded so that described goods to be shrunk to its uncovered side end close each other.According to the present invention, although described cavity design becomes an end of tongue spare portion to depart from the interior mating surface of front end of coupler body slightly, if curved portions is constituted as described above, so, after molded, described curved portions will because of contraction towards so that the distortion of the close each other direction of two openends.Its result, an end of tongue spare portion can contact with mating surface in the front end of coupler body or mutually near until a kind of like this degree: swivel hook is not ineffective.
According to tradition, swivel hook is the outside that the front end that is molded into retainer is positioned at the arc tips of coupler body, and after molded, and retainer can strain, thus described front end just with an inner surface of coupler body on described front end cooperate upper thread to mesh.According to the present invention, can exempt a kind of like this operation, that is, and with making the retainer strain, with its front end manufacture be arranged on coupler body one inner surface on the front end mating surface match, therefore, the present invention can boost productivity, and reduces production costs.
May have such a case, that is, the aforementioned contraction of tongue spare portion is very little, between tongue spare portion end and coupler body goods a gap is just arranged like this, thereby this gap can not keep swivel hook to work too greatly.Therefore, preferably, a projection is arranged on the interior mating surface of swivel hook, described projection is come out towards the projection of described tongue spare portion.
In described mould, if being used for the die cavity of molded projection forms and be used for the die cavity of interior assembled end of molded coupler body and be communicated with, then the projecting end of described projection almost can not contact with the end of tongue spare portion, and swivel hook just may lose effect like this.Therefore, preferably,, form a thin portion, make the front end outer surface of it and tongue spare portion be linked to be an integral body at the projecting end of described projection by molded.
In other words, in mould, be used for the die cavity of molded described projection be formed into be used for molded described coupler body interior assembled end die cavity and be used for the die cavity of molded described tongue spare portion end and be connected.In this case, just form very narrowly being used for the die cavity of molded described projection and the groove that is used between the die cavity of molded described tongue spare portion end.Adopt this set scheme, when carrying out when molded, the end of the top of described projection and described tongue spare portion can couple together by a thin portion, and, when molded, the end of tongue spare portion can be located near the end of described projection.Because this connection is thinner, therefore, rupture easily during use first that it can be after molded, and the end of described tongue spare portion can reliably contact with the end of projection, an enough little gap is perhaps arranged, thereby can maintain the effect of swivel hook.
Preferably, a connection piece is set, thereby can is connected in aggregates with the inner surface area that the side of described coupler body is being faced above-mentioned zone the zone of that the most close described coupler body inner surface in the described retainer curved portions.
The curved portions of described retainer is easy to be out of shape because of the contraction that takes place in the molding process, thereby leaves the inner surface of coupler body.So when being applied to a very big external force on the retainer, it can rupture at a part place that links to each other with base portion.When the zone of that the most close coupler body inner surface of retainer can couple together by little connector with the coupler body inner surface area of facing mutually, can prevent to move away the inner surface of coupler body because of contraction distortion makes retainer in the molding process.And even a very big external force is acted on the retainer, yielding tongue spare portion also can be in described connector place strain, thereby can prevent the problem such as fracture.
According to the present invention, the shape of described bottom and curved portions, especially curved portions is specific.Preferably, described curved portions is towards an inner surface of coupler body, from the bending of the centre position of bottom, and comes out towards an inner surface projection of coupler body.Perhaps, described curved portions begins from a top of described bottom, crooked continuously towards an inner surface of coupler body, and comes out towards the described inner surface projection of coupler body.Again or, described curved portions from a top of bottom, crooked continuously towards base portion, thereby come out towards an inner surface projection of coupler body.
According to the present invention, the shape of described tongue spare portion is specific.Just, described tongue spare portion is made of a narrow plate member, described narrow plate member from an end of curved portions, linearly or arc extend upwardly to described coupler body one in mating surface.

Below in conjunction with accompanying drawing, based on several preferred embodiments, present invention is described.In the swivel hook 1 in illustrative example, one is used for band connecting ring that a belt or analog are linked to each other with a hook body and described hook body connects into them and can rotate relative to one another around along its length a center line, as U.S. Patent No. 5,566, disclosed in 428 like that.But, also can described band connecting ring and described hook body is separately molded, and after molded separately, they are assembled together, as disclosing among the European patent No.0099577 A1.
Fig. 1-Fig. 3 shows the first embodiment of the present invention.Fig. 1 is the front view of swivel hook 1, and Fig. 2 is its side view, and Fig. 3 is its vertical view.See also these accompanying drawings, a hook body 11 comprises: a disc shaped base 11a; One comes out to be the coupler body 11b of a hook shape from the surperficial projection of base portion 11a; An and retainer 11c, it comes out from the described surperficial projection of base portion 11a, and mutually opposed with the inner surface towards coupler body 11b one front end of the bottom of coupler body 11b, described hook body also comprises: one comes out, passes the shallow bid shape engaging piece 11e of narrow footpath neck 11d from another surperficial projection of base portion 11a.
On the other hand, the band connecting ring 12 that is meshed with aforementioned engaging piece 11e comprises a c-shaped basically band connecting portion 12a, it has a belt jack 12a ' and an engaging piece 12b, described engaging piece can be with the left and right end free rotary ground supporting of connecting portion 12a, and is meshed with the engaging piece 11e of hook body 11.According to this embodiment, aforementioned hook body 11 and band connecting ring 12 are molded as a kind of like this state simultaneously, that is, engaging piece 11e is meshed with engaging piece 12b.The method that is disclosed in this method of moulding and the U.S. Patent No. 5,566,428 is essentially identical, therefore, repeats no more herein.
Though the structure of coupler body 11b is different with a kind of traditional structure,, retainer 11c has feature structure of the present invention.Be understandable that from Fig. 1 retainer 11c comprises: a bottom 11c-1, make by being down trapezoidal plate substantially this bottom, and described plate is from the base portion 11a of swivel hook main body 11, obliquely and point-blank projection is come out and had predetermined hardness and thickness; One curved portions 11c-2, it is towards an inner surface of the described bottom of coupler body 11b, come out from a mid portion projection of the described bottom end vicinity of bottom 11c-1, and the U-shaped in general bending, thereby make the space between the front end of described curved portions and bottom 11c-1 outwards uncovered; And a 11c-3 of tongue spare portion of narrow plate, it from the end arc of described curved portions 11c-2 extend out, thereby it " is contacted with the interior mating surface 11b of the curved end 11b ' of aforementioned coupler body 11b.
Bottom 11c-1 is not directly related with strain, but makes: even apply a certain size strong external force, its base portion can not rupture yet, that is, it is configured to have a for example skirt section.On the other hand.Although aforementioned band connecting ring 12 is in design with traditional different, its structure and work effect do not have difference.Therefore, this paper omits the description to band connecting ring 12, will the work effect of hook body 11 be described.
According to first embodiment, if the external force of a common size is acted on the 11c-3 of tongue spare portion of retainer 11c, this external force nearly all is used for the strain of curved portions 11c-2.Pointed as the dotted line among Fig. 1, the front end of the 11c-3 of tongue spare portion will contact with the inner surface of coupler body 11b swimmingly at a P1 place.Thereby if remove described external force, aforementioned curved portions 11c-2 will be returned to its original-shape, and by described restitution, the 11c-3 of tongue spare portion will get back to its home position P2, thereby the 11c-3 of tongue spare portion is contacted with the front end mating surface of coupler body 11b.
Put on the described swivel hook and described retainer when fracture as a beyond thought external force, in most applications, it ruptures with the external force on the bottom that directly puts on described retainer.But even a very big external force is put on the bottom 11c-1 of retainer 11c of present embodiment, it can strain yet, and since the intensity of bottom 11c-1 greater than other parts, therefore, its extremely difficult fracture.In addition, bottom 11c-1 plays a part block for curved portions 11c-2, like this, just can prevent curved portions 11c-2 and the 11c-3 of tongue spare portion fracture.
The aforementioned structure of the retainer 11c of present embodiment can guarantee the high efficiency production of swivel hook 1.Usually, in molded, when a molded products is taken out from the die cavity of injection mould, described molded products will shrink.Especially, when molded products during c-shaped or U-shaped, because the temperature distributing disproportionation of molded products when molded, its uncovered side end will shrink towards a direction, make both ends close each other.For example, be arranged in by the P3 place, position shown in Fig. 1 solid line if the die cavity of injection mould is a front end that is designed to retainer 11c, then the front end of molded products will be deformed into by the position P2 shown in the dotted line among Fig. 1.
The present invention has adopted this structure when molded.If the cavity design of injection mould (not shown) becomes the front position of retainer 11c to be positioned at the P3 position, then " will slightly inwardly depart from, therefore, the peristome that a molded products will be made into curved portions 11c-2 is narrower for the interior mating surface 11b of coupler body 11b." move, thereby make it and interior mating surface 11b " contacts or approaching mutually until a kind of like this degree then, to make the interior mating surface 11b of the front end outer surface of the 11c-3 of tongue spare portion towards coupler body 11b: swivel hook 1 does not lose effect.
Therefore, according to present embodiment, below a kind of like this manufacturing procedure just becomes optional, promptly, wherein the goods front end that is molded into retainer 11c is positioned at the mating surface 11b with coupler body 11b " opposite external side, thereby and after molded, can make the front end of retainer 11c and the interior mating surface 11b of coupler body 11b by restoring force with the inside that retainer 11c strain makes it move to coupler body 11b " contact, therefore, can boost productivity, and reduce production costs.
Fig. 4 is the front view of the hook body 11 of second embodiment of the invention.See also Fig. 4, aforementioned retainer 11c has a feature structure.Retainer 11c comprises: a bottom 11c-1, and it comes out and has the shape identical with first embodiment from base portion 11a projection; One curved portions 11c-2, it towards the inside of coupler body 11b, from the top of bottom 11c-1, projection substantially vertically comes out, and roughly is the outside C oxbow of opening; And the 11c-3 of tongue spare portion, it is towards the interior mating surface 11b of coupler body 11b " extend linearly, vertical substantially with the top of curved portions 11c-2.Present embodiment can produce the working effect identical with first embodiment.But when the external force with a common size acted on retainer 11c, the strain of curved portions 11c-2 will be greater than first embodiment, and easily manufactured.
Fig. 5 is the front view of the hook body 11 of third embodiment of the invention.See also Fig. 5, retainer 11c has a feature structure.Retainer 11c comprises: a bottom 11c-1, and it comes out and has the shape identical with first embodiment from base portion 11a projection; One curved portions 11c-2, it is towards the inner surface of coupler body 11b and coupler body 11b, from the top of bottom 11c-1, projection is come out obliquely, and roughly is inverted U-shaped bending at it near the position of base portion 11a; And the 11c-3 of tongue spare portion, it is towards the interior mating surface 11b of coupler body 11b ", extend linearly from the top of curved portions 11c-2.Present embodiment also can produce the working effect identical with second embodiment.
Fig. 6 and Fig. 7 show and Fig. 4 and the aforementioned second and the 3rd embodiment the corresponding the 4th and the 5th embodiment shown in Figure 5.In the swivel hook 1 of these embodiment, hook body 11 is made for one, thereby coupler body 11b is connected as a single entity by the bottom 11c-1 of the U-shaped bending, thicker base portion 11a and retainer 11c.When base portion 11a was inserted band connecting ring 12, described base portion can freedom unsteadily be supported.
According to the 4th embodiment shown in Figure 6, retainer 11c comprises: an end from base portion 11a, be basically parallel to the bottom 11c-1 of coupler body 11b projection; One curved portions 11c-2, it is towards the inner surface of coupler body 11b, come out from an end, the projection substantially vertically of bottom 11c-1, and roughly is the outside C oxbow of opening; And the 11c-3 of tongue spare portion, it is from the end of curved portions 11c-2, towards the interior mating surface 11b of coupler body 11b ", substantially vertically linearity extends out.
According to the 5th embodiment shown in Figure 7, retainer 11c comprises: an end from base portion 11a, be basically parallel to the bottom 11c-1 of coupler body 11b projection; One curved portions 11c-2, it from the end of bottom 11c-1, towards the inner surface of base portion 11a and coupler body 11b obliquely projection come out, and near the place of base portion 11a, roughly be inverted U-shaped bending; And the 11c-3 of tongue spare portion, it from the end of curved portions 11c-2, " extend out towards the interior mating surface 11b of coupler body 11b arc.
Fig. 8 to Figure 10 shows the sixth embodiment of the present invention.
In the present embodiment, with each embodiment described above three differences are arranged.First is not both: projection 11f is the interior mating surface 11b that is made into from coupler body 11b, and " projection is come out, and the thin 11f ' of portion is with Unitarily molded and link to each other with the end of retainer 11c.Second is not both: curved portions 11c-2 and coupler body 11b are connected with each other by little connector 11g.The 3rd is not both: a fin 11h is arranged on the inner surface of curved end 11b ' of coupler body 11b, be adjacent to projection 11f.The height of fin 11h is identical with the height of the extended line of an inner surface of the end of the 11c-3 of tongue spare portion.At the two ends of fin 11h, the height of fin reduces gradually towards the bending direction of curved end 11b ', thereby can fuse with the described inner surface of coupler body 11b.
In the present embodiment, the curved portions 11c-2 of retainer 11c shrinks and causes the deflection that is out of shape less when molded.Gap when therefore, molded is also less.Therefore, in the end of the 11c-3 of tongue spare portion of swivel hook and be positioned at the mating surface 11b of coupler body 11b end " between may form the gap that for a moment reduces this swivel hook effect.For this reason, the interior mating surface 11b of coupler body 11b " is provided with a projection 11f towards the front end outer surface projection of the 11c-3 of tongue spare portion.Therefore, after molded contraction, the end of the 11c-3 of tongue spare portion can reliably contact with the projection end of projection 11f.
But, even employing said structure, if molded operation is to carry out in a kind of so not shown mould, promptly, the die cavity of molded projection 11f of being used for of described mould is disconnected with being used for the die cavity of the 11c-3 of tongue spare portion of molded retainer 11c, and then the projecting end of projection 11f also almost can not contact with the outer surface of the 11c-3 of tongue spare portion.As a result, swivel hook may lose effect.
Therefore, in the present embodiment, the thin 11f ' of portion in projection 11f end is that the front end outer surface 11c-3 ' that is molded into the 11c-3 of tongue spare portion is linked to be an integral body.In other words, in not shown mould, being used for the die cavity of molded projection 11f is to be made into and to be used for the die cavity of the 11c-3 of tongue spare portion of molded retainer 11c and to be connected.To be narrower than the normal conditions submarine gate being used for the described not shown die cavity of molded projection 11f and a groove that is used between the described not shown die cavity of the molded tongue spare 11c-3 of portion.
Adopt this set scheme, the top of projection 11f can be connected by the thin 11f ' of portion with front end outer surface 11c-3 '.And owing to shrink when molded, the front end outer surface 11c-3 ' of the 11c-3 of tongue spare portion just becomes near the top of projection 11f.Because this connection realizes with the thin 11f ' of portion, therefore, the thin 11f ' of portion can and disconnect easily with fastener operation, and it is after molded that described fastener is done operation, make a not shown associating connecting ring first fastener on the coupler body 11b of swivel hook 1.In this case, the front end outer surface 11c-3 ' of the 11c-3 of tongue spare portion also can reliably contact with the top of projection 11f, and an enough little gap is perhaps arranged, thereby can maintain the effect of swivel hook.
On the other hand, a kind of like this projection 11f is set causes a kind of like this possibility, promptly, even the interior mating surface 11b of coupler body 11b " and the front end outer surface 11c-3 ' of the 11c-3 of tongue spare portion thus between the gap be to open wide to such an extent that the enough wide connecting ring that can make passes through; not shown associating connecting ring and the swivel hook 1 of fastener on the hook portions of coupler body 1b broken off relations, but projection 11f still can hinder and thisly breaks off relations very easily.The 3rd difference as described above is provided with for addressing this problem.
Specifically, if will have the curved end 11b ' that the fin 11h of aforementioned structure is arranged on coupler body 11 is adjacent on the inner surface of projection 11f, so, when the swivel hook 1 that makes described not shown associating connecting ring and present embodiment breaks off relations, described connecting ring can be directed to the height of projection 11f with fin 11b, and described connecting ring and swivel hook 1 are broken off relations.If can ignore material cost, then can projection 11f and fin 11h is integrally molded.
As mentioned above, the curved portions 11c-2 of retainer 11c is easy to leave because of the contraction distortion that takes place in the molding process inner surface of coupler body 11b.So in the time of on a very big external force being applied to retainer 11c, the 11c-3 of tongue spare portion will rupture at a part place that links to each other with bottom 11c-1 together with curved portions 11c-2.
Therefore, as mentioned above, regional 11c-2 ' the curved portions 11c-2 of retainer 11c, the most close coupler body 11b, can couple together by little connector 11g with the inner surface area 11b-1 of coupler body 11b, therefore, curved portions 11c-2 can not leave the inner surface of coupler body 11b because of the contraction distortion in the molding process.And, even a very big external force is acted on the retainer 11c, strain also can take place in tongue spare portion 11c-3 easily, uniquely, thereby makes retainer 11c be easy to deform at connector 11g place, so just can prevent the problem such as fracture.
But if the width of connector 11g is identical with the width of the 11c-3 of tongue spare portion, so, the amount of contraction in the curved portions 11c-2 molding process will reduce.Therefore, people wish to make the size of connector 11g as far as possible little.Meanwhile, connector 11g also should have enough big hardness, thereby can not damaged easily because of the external force effect.Therefore, connector 11g should have a kind of like this size, that is, it can not be subjected to the influence of aforementioned contraction, and has suitable hardness.Described size can suitably be determined according to its purposes.
Can see significantly from the above description, can also make the improvement of variety of way to swivel hook of the present invention, and the present invention not be subjected to the restriction of each embodiment described above.
